title: Interactions between amphotericin B and nitroimidazoles against Candida albicans.
abstract: This work proved that nitroimidazole antiprotozoal agents, such as metronidazole, ornidazole, secnidazole and tinidazole, in concentrations of up to 64 micrograms ml-1 did not present any antifungal activity against 17 strains of Candida albicans. The combination of each drug with amphotericin B showed the occurrence of variable interactions according to the studied strain. Promising results were observed based on synergistic and additive interactions of the polyene with the metronidazole; the inhibitory and lethal activities of the drugs were potentiated against all strains in concentrations reachable in vivo.
